Description

System and method for realizing multi-mode terminal to simultaneously receive multi-network messages

The present invention relates to the field of communications technologies, and in particular, to a system and method for implementing a multi-mode terminal to simultaneously receive multi-network messages in a multi-mode network. Background of the invention

With the development of science and technology, networks of various standards continue to appear. For example, the cdma2000 system, HRPD system, WCDMA system, etc., and the network of the same standard can be divided into networks of different frequency bands. For example, the cdma2000 system includes IS95, cdma2000 lx, HRPD, and IxEV-DV four standard phases.

In the case where networks of different standards and / or frequency bands are superimposed and operated in a certain area, they can provide corresponding services to terminals supporting their own networks. However, since there is no communication interface between the multi-mode networks, when a multi-mode terminal supporting the multi-mode network resides in one of the networks, it cannot receive system messages of the other network. For example, in a multimode network including a cdma2000 system, an HRPD system, and a WCDMA system, these systems are relatively independent. Moreover, there is no other interface between the cdma OO system and the HRPD system except that the same PDSN can be connected. There is no network interface between HRPD system and WCDMA system, nor is there any network interface between cdma2000 system and WCDMA system. For a multi-mode terminal that supports more than one of the above systems at the same time, if it resides in one of the networks, if it wants to receive paging messages or system messages from other networks, it must switch to the frequency where the other networks are located and answer the call regularly. Call message or system message. In order for a multi-mode terminal to receive paging messages and system messages from multiple systems, it is necessary to frequently switch searches between multiple networks. For the terminal, the power consumption is very large. For another example, FIG. 1 is a schematic diagram of a connection between a cdma2000 lx system and an HRPD system. For convenience, the cdma2000 lx is referred to as lx and the HRPD is referred to as DO. Referring to FIG. 1, the dashed box on the left is the lx system, and the dashed box on the right is the DO system. Both systems are connected to the same packet data service node (PDSN) at the same time, and both can provide packet data services. According to the 3GPP2 standard, the networking structure of the lx system and the DO system is relatively independent. Except that the two systems can be connected to the same PDSN, there is no other interface.

Based on the above network structure, in the case that the lx network and the DO network are superimposed, both the lx network and the DO network can provide packet data service services. For a lx / DO dual-mode terminal with only one set of transmitting and receiving devices, The terminal MS / AT resides in the lx network, and the lx network provides packet data services for this dual-mode terminal; when the dual-mode terminal MS / AT resides in the DO network, the DO network provides packet data services.

According to the standard network structure diagram, when the MS / AT resides on the DO network, the lx network delivers the MS / AT paging. Since the lx network and the DO network are established on different frequency points, the MS / AT will not be able to receive Paging from the lx network.

The standard stipulates that, in multiple networks with different frequency points, in order for MS / AT to be able to receive paging from lx when performing packet data service services on the DO network, it must frequently switch to the lx network and actively answer lx. System messages and paging messages. Therefore, MS / AT needs to frequently switch searches between the two networks. MS / AT consumes a lot of power, and it also has a relatively large impact on some data services that require high real-time performance. Summary of the invention

In the following, a specific embodiment of a multimode system including two inter-frequency networks is used to describe the technical solution of the present invention in detail.

As shown in FIG. 4, compared with the prior art in this embodiment, the lx BSS / PCF in the lx network is connected to the DO AN / PCF of the DO network through the X interface. The x interface is used to transfer messages between systems between two networks.

With the system shown in FIG. 4, when the dual-mode terminal MS / AT resides in the DO network, or the DO network provides packet data services to the terminal, the system message or paging from the lx network can be answered. The page here can be a voice page or a packet domain page. The specific implementation process is as follows:

For example, the user can determine whether to switch to another network or ignore the paging message based on the paging information from the second network paging message.

The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention shall be included in the present invention. Within the scope of protection.
